Publication number: 20200404149Abstract: A method for automatically determining exposure settings for an image acquisition system comprises maintaining a plurality of look-up tables, each look-up table being associated with a corresponding light condition and storing image exposure settings associated with corresponding distance values between a subject and the image acquisition system. An image of a subject is acquired from a camera module; and a light condition occurring during the acquisition is determined based on the acquired image. A distance between the subject and the camera module during the acquisition is calculated.Type: ApplicationFiled: June 29, 2020Publication date: December 24, 2020Applicant: FotoNation LimitedInventor: Istvan ANDORKO

Publication number: 20200387728Abstract: This disclosure describes, in part, devices and techniques for performing biometric identification for an electronic device. For instance, the electronic device may include one or more near-infrared illuminators that output near-infrared light. The one or more near-infrared illuminators may be located in or on a bezel and/or a display of the electronic device. The electronic device may also include an imaging device that generates first image data representing the near-infrared light and visible light. After generating the image data, the electronic device may process the first image data using one or more image processing techniques to generate second image data representing a near-infrared image and third image data representing a visible image. The electronic device may then analyze the second image data and/or the third image data using one or more biometric identification techniques. Based on the analysis, the electronic device may identify a person possessing the electronic device.Type: ApplicationFiled: May 26, 2020Publication date: December 10, 2020Applicant: FotoNation LimitedInventors: Istvan ANDORKO, Petronel BIGIOI

Publication number: 20200364441Abstract: An image acquisition system determines first and second sets of points defining an iris-pupil boundary and an iris-sclera boundary in an acquired image; determines respective ellipses fitting the first and second sets of points; determines a transformation to transform one of the ellipses into a circle on a corresponding plane; using the determined transformation, transforms the selected ellipse into a circle on the plane; using the determined transformation, transforms the other ellipse into a transformed ellipse on the plane; determines a plurality of ellipses on the plane for defining an iris grid, by interpolating a plurality of ellipses between the circle and the transformed ellipse; moves the determined grid ellipses onto the iris in the image using an inverse transformation of the determined transformation; and extracts an iris texture by unwrapping the iris and interpolating image pixel values at each grid point defined along each of the grid ellipses.Type: ApplicationFiled: May 13, 2019Publication date: November 19, 2020Applicant: FotoNation LimitedInventors: Brian O'SULLIVAN, Barry MCCULLAGH, Serghei CARATEEV, Istvan ANDORKO, Petronel BIGIOI

Publication number: 20200272719Abstract: A biometrics-enabled portable storage device may store and secure data via biometrics related to a user's iris. The biometrics-enabled portable storage device may include a camera that captures image data related a user's iris and stores the image data to enroll the user for use of the biometrics-enabled portable storage device. To unlock the data, a user aligns the camera with their iris using a hot mirror and the camera captures iris data for comparison with the iris image data stored during enrollment. If the two sets of image data match, the biometrics-enabled portable storage device may be unlocked and the user may access data stored on the biometrics-enabled portable storage device. If the two sets of image data do not match, then the biometrics-enabled portable storage device remains locked.Type: ApplicationFiled: February 25, 2020Publication date: August 27, 2020Inventors: Istvan Andorko, Petronel Bigioi, Darragh Ballesty

Publication number: 20200074174Abstract: An image processing method for iris recognition of a predetermined subject, comprises acquiring through an image sensor, a probe image illuminated by an infra-red (IR) illumination source, wherein the probe image comprises one or more eye regions and is overexposed until skin portions of the image are saturated. One or more iris regions are identified within the one or more eye regions of said probe image; and the identified iris regions are analysed to detect whether they belong to the predetermined subject.Type: ApplicationFiled: November 8, 2019Publication date: March 5, 2020Applicant: FotoNation LimitedInventors: Istvan ANDORKO, Alexandru DRIMBAREAN, Peter CORCORAN

Patent number: 10467469Abstract: An optical system for an image acquisition device comprises an image sensor comprising an array of pixels including pixels sensitive to IR wavelengths for acquiring an image. A lens assembly includes a collecting lens surface with an optical axis, the lens assembly being arranged to focus IR light received from a given object distance on the sensor surface. The lens assembly includes at least a first reflective surface for reflecting collected light along an axis transverse to the optical axis so that a length of the optical system along the optical axis is reduced by comparison to a focal length of the lens assembly.Type: GrantFiled: February 25, 2016Date of Patent: November 5, 2019Assignee: FotoNation LimitedInventors: Alexander Goncharov, Christopher Dainty, Istvan Andorko, Peter Corcoran

Patent number: 10152631Abstract: An optical system for an image acquisition device comprises a filter comprising a central aperture arranged to transmit both visible and selected near infra-red (NIR) wavelengths and a peripheral aperture arranged to block visible wavelengths and to transmit the NIR wavelengths. An image sensor comprises an array of pixels including pixels sensitive to visible wavelengths and corresponding pixels sensitive to the NIR wavelengths. A lens assembly is axially located between the filter and the image sensor and comprises a plurality of lens elements. The lens elements are arranged to simultaneously focus NIR light received from a given object through central and peripheral apertures of the filter and visible light received from the object through the central aperture onto the sensor surface.Type: GrantFiled: December 8, 2015Date of Patent: December 11, 2018Assignee: FotoNation LimitedInventors: Christopher Dainty, Alexander Goncharov, Istvan Andorko, Peter Corcoran, Petronel Bigioi

Publication number: 20180173951Abstract: In an embodiment, a method comprises determining, by a portable device, image capturing conditions by analyzing contents of a particular digital image of one or more first digital images captured by one or more image capturing devices. It is also determined whether the image capturing conditions indicate indoor image capturing conditions. If the image capturing conditions indicate indoor image capturing conditions, then it is determined whether the particular digital image includes a depiction of at least one eye. If so, an iris region, depicting the at least one eye, is segmented in the particular digital image. If the segmented iris region does not include iris valid information, then one or more image capturing devices capture one or more second digital images having an enhanced contrast. If the one or more second digital images include iris valid information, then iris code is extracted from the one or more second digital images.Type: ApplicationFiled: November 13, 2017Publication date: June 21, 2018Inventors: Istvan ANDORKO, Alexandru DRIMBAREAN
